Costco's 5 Best Seasonal Items Of 2026 — So Far

While you may have signed up for a Costco membership to get a good deal on toilet paper and gas, it's the food finds that turn casual shoppers into Costco devotees. Some beloved eats, like the croissants and the rotisserie chicken, are always available, but others — particularly bakery items and prepared foods — come and go with the seasons, adding an extra layer to the warehouse store's infamous treasure hunt-style shopping experience.

We're three-quarters of the way through the year, and Costco has embraced the seasons with limited-time items that shoppers love. From returning favorites to new additions, there's truly something new to find on every shopping trip. And since Costco is known to put out seasonal items well in advance (we saw you show up in July, giant skeleton), it's only a matter of time before even more seasonal items make their way into our shopping carts.

We dug through Reddit posts, went deep on Facebook and Instagram, and checked our own shopping history to find Costco's best seasonal items of 2026 to date. These items were chosen based on reviews from Costco customers collected from social media platforms. All prices are based on Denver-area Costco locations. Prices are as of the date of publication and may vary based on region.

As spring arrived, Costco treated shoppers to harvests of stone fruit and berries, as well as a brand new item in the bakery. The Kirkland Signature Peaches and Cream Pastries were the perfect grab-and-go treat, pairing flaky pastry with two fillings: A tangy combination of cream cheese and Greek yogurt, and dollop of sweet peaches. "This was really good! It had texture more like a Danish than a croissant," said one reviewer on Facebook. Another Facebook reviewer offered this tip: "These are incredible when you heat them up for a few seconds!" Instead of the microwave, consider putting a pastry like this into the air fryer to warm up the filling and enhance the flakiness of the pastry crust. Better yet? Get inspired by this Instagram reviewer and add some ice cream for a pie à la mode vibe.

A pack of eight Kirkland Signature Peaches and Cream Pastries was $11.99.

Canned coffees make it easy to caffeinate on the go, and Costco has been treating us to various seasonal La Colombe draft latte flavors all year. This summer, it was the S'Mores Draft Latte that stood out. We gave the mocha flavor high marks in our ranking of canned iced coffees, and the s'mores flavor takes that chocolatey note to the next level. The drink uses lactose-free milk, real cocoa, and La Colombe's espresso roast for a rich coffee flavor, paired with notes of graham cracker and marshmallow. "Just the right amount of sweetness and texture while letting the rich coffee flavor flow through," says one reviewer on the La Colombe website. Adds another reviewer on the same site: "La Colombe does a fantastic job of balancing the coffee-to-flavor ratio for a balanced taste profile."

A pack of 12 La Colombe S'Mores Draft Lattes was $22.99.

The behemoth pumpkin pie is one of the most beloved pumpkin items at Costco every fall, but it isn't the only pumpkin dessert shoppers adore. The Kirkland Signature Pumpkin Cheesecake tops pumpkin cheesecake with a thick coating of pumpkin whipped topping, all on a graham cracker crust. "It's absolutely delicious. I recommend everyone try it if you like pumpkin flavored stuff," says one Reddit user. Another reviewer suggests you stock up: "Our house got 1 last year. Devoured it in 3 days. Then bought a 2nd one," they revealed. Afraid you won't finish it all? Leave it to Reddit to solve your problems. "We buy a couple of them over the season, take home, and slice and freeze the slices so we can enjoy any time of the year." Costco doesn't sell pumpkin cheesecake year-round, but that doesn't mean you can't enjoy it whenever you want.

Some people might not find a trip to Costco romantic, but that doesn't mean the store can't get in the Valentine's Day spirit. In early 2026, the Costco bakery released a pack of heart-shaped madeleines, with six raspberry madeleines with raspberry filling and three butter madeleines with a chocolate-hazelnut filling and a chocolate drizzle, perfect for the sweetest of holidays. "These are SO moist, and the fillings (both the raspberry & Nutella) are perfection. Totally worth the tenner," says one fan on Reddit. Plus, shoppers appreciate that the vibrant red color isn't from a hefty dose of red 40. "They use beet concentrate for color," another Reddit reviewer notes. Are they authentic French madeleines? No, but these tasty holiday sweets were a big hit while they were available — plus the Costco bakery is now baking up 12-packs of traditional madeleines for your year-round enjoyment.

A pack of nine Kirkland Signature Filled Heart Madeleines was $9.99.

Costco's macaroni and cheese is a cult favorite, and as holiday season rolls around, the cheesy casserole gets an indulgent upgrade with the addition of chunks of cold water lobster meat. In 2026, however, Costco treated us to an extra opportunity to enjoy the lobster macaroni and cheese by releasing it (for a limited time and only at certain locations) in February, as well. "Lobster throughout, not just on top," says one fan on Instagram. "Worth every penny. Our entire family devoured it." A reviewer on Reddit offered a tip to keep the lobster meat succulent: "I'd recommend mixing the top claw meat into the rest of the mac before covering in foil and baking it," they suggested. Feeling particularly fancy? When the lobster mac and cheese returns to stores this holiday season, consider enhancing it even further with one of our favorite macaroni and cheese additions.

Kirkland Signature Lobster Mac and Cheese was around $7.00 per pound.
